Firewall Rules to Control Network Access
Your modem router has a firewall that blocks unauthorized access to your wireless network
and permits authorized inbound and outbound communications. Authorized communications
are established according to inbound and outbound rules. The firewall has the following two
default rules. You can create custom rules to further restrict the outbound communications or
more widely open the inbound communications:
Inbound. Block all access from outside except responses to requests from the LAN side.
•
Outbound. Allow all access from the LAN side to the outside.
•
Configure Firewall Rules
The Firewall Rules screen lets you configure custom rules to make exceptions to the default
rules. Exceptions can be based on the service or application, source or destination IP
addresses, and time of day. You can log traffic that matches or does not match the rule and
change the order of rule precedence. See
services.
All traffic attempting to pass through the firewall is subjected to the rules in the order shown in
the Rules table from the top (highest precedence) to the default rules at the bottom. In some
cases, the order of precedence is important to determine which communications are allowed
into or out of the network.
